Description
BACKGROUND OF THE INVENTION
A known stone fruit biscuit machine of Japanese Patent No. 61195991 and
U.S. Pat. No. 4,711,166 has flowing operations of material reserving,
material restoring, planing, sucking, baking and cooling. However, this
machine has been found to have many drawbacks as follows.
1. A reserve chamber has an excessive height, more than two meters, quite
inconvenient to pour a heavy bag of material stone fruit into the chamber.
2. The reserve chamber is shaped long and rectangular and the upper surface
has to be flattened in order to equally force the stone fruit therein to
be sent out of a plurality of tubes.
3. The reserve chamber is located very high and an examination windown for
checking the content material is liable to reflect light, difficult to
check the volume of material therein.
4. The reserve chamber has not a complete structure to dispensing material
in definite pressure and definite volume.
5. A blade in a planing device has a large dimensions and thin, and an
intermediate portion of a blade frame produces disfigurement caused by
large pressure coming from many material conveying tubes, and consequently
planed stone fruit pieces are not all equally thin.
6. A sucking plate cannot suck all of planed stone fruit pieces to cause
finished products incomplete with cavities and notches.
7. The planing device is too complicated and large, hardly cooperative in
different processes, so that planed stone fruit pieces may drop down in
the process of sucking to scatter around on the ground or in the bottom of
the machine.
8. Cleaning scattered stone fruit pieces increases producing cost, not
economical.
9. Planed stone fruit pieces are sucked mainly in the middle portion, and
those in both sides are not sucked with sufficient force, liable to drop
down.
10. A sucking plate and cone-shaped sucking holes do not function as
planned to permit planed stone fruit pieces drop down when a fan is
stopped, but in practical operation oil coming out of stone fruit can
block up the sucking holes and they stick there.
11. A fan blowing the sucking holes will have growing load and produce
noise by repeated blockage of the sucking holes.
SUMMARY OF THE INVENTION
This invention has been devised to improve the material reserving,
restoring, dispensing and planing and sucking devices in the
above-mentioned automatic stone fruit machine, with better features as
follows.
1. It makes use of a blower to assist to convey stone fruit in a reserve
tank mounted under a machine table through a conduit in a volume
pre-determining chamber. Then a worker only checks the content of the
reserve tank, without necessity of checking the volume pre-determining
chamber, or of climbing up a conventional machine for checking a high
positioned reserve chamber.
2. It includes an inverted U-shaped exit tube moved by a non-rod air
cylinder to move back and forth above the volume predetermining chamber
and drop stone fruit in the chamber in average condition so as to dispense
equally stone fruit in a plurality of exit tubes.
3. Stone fruit in each exit tube above a blade are pressed down with a
preset definite pressure so that the stone fruit in each exit tube are
closely packed to be planed into equally thin flat pieces. In addition,
the pressure can be adjusted according to sizes, hardness, shapes of stone
fruit.
4. When planed stone fruit are planed, the planed thin pieces are quickly
sucked down by a sucking plate below the blade, possible to be orderly
placed on the sucking plate.
5. Planing and sucking process are well coordinated to suck planed stone
fruit pieces to drop on the sucking plate in order, without falling down
on the ground or the bottom of the machine, and consequently quality of
finished products can be secured perfect.
6. An upper and a lower blade frame have ribs and pinch the blade, two
packings and separating plate between them, having enough strength to
endure pressure coming from a plurality of material conveying tubes so
that an intermediate portion of the blade with the frame cannot sag down
to a result that all of planed stone fruit pieces are equally thin.
8. Its whole size is smaller than the conventional one.
9. It includes a hole cleaner with needles to clean sucking holes in the
sucking plate every time when Planed stone fruit pieces are dropped from
the sucking plate to a baking plate so that no stone fruit pieces are kept
stuck in the sucking plate.
10. Each time when the needles finish operation, stone fruit bits in the
sucking holes can be cleaned off, never blocked, so a blower does not have
heavy load, nor produce noise.
11. Operation of sucking and placing planed stone fruit pieces is quite
accurate, and so planed stone fruit pieces do not fall down on the ground
or in the bottom of the machine.
12. The whole structure of the machine has been made and tested, having
better function than the conventional one.

convey unit 106 to move forward intermittently baking plates 108 with
bottom dough on their surfaces to a planing device 4 which planes stone
fruit coming out of a material volume pre-determining chamber and drops
planed stone fruit pieces on a sucking plate 52, which is invertedly moved
with planed stone fruit pieces to a baking plate 108, then the planed
stone fruit being dropped on the baking plate 108 which is then conveyed
to a second sprayer 105 to spray facial dough on the bottom dough with
stone fruit pieces on the baking plate 108 and to be sent into a baking
stove 111 for baking. The material volume pre-determining chamber 3
receives material stone fruit from a material reserve tank 2.
The material reserve tank 2 shown in FIG. 2, has a tank body 21, an upper
cap 22, a vibrating bottom plate 23, a material dealing-out case 24, a
changeover valve 25, and a conduit 26. The tank body 21 is mounted on the
machine body 1 having a inlet hopper 221 to receive material fruit from a
door 121 in a side wall of the machine body 1. A control shutter 213 is
provided in the bottom of the tank body 21 to control the volume of the
material stone fruit passing out of the dealing-out case 124, and the
material drops in a hopper 241 and then into a conduit 26 connected with a
blower (not drawn in the Figures) and then is sent into the material
volume pre-determining chamber 3 controlled by the changeover valve 25,
which will be described later. The vibrating bottom plate 23 is fixed on
the inner bottom of the tank body 21 and supported on a shock-absorbing
base 231. The material dealing-out case 24 is sustained by shock-absorbing
springs 241, and air pressure vibrators 232, 243 are respectively provided
under the vibrating bottom plate 23 and the case 24, assisting to send
smoothly material into the conduit 26.
The material volume pre-determining chamber 3 shown in FIGS. 3 and 4 has
its body 31 mounted on the machine body 1, a coneshaped cap 32, an
adjusting plate 321 and a hopper 322 forming an upper chamber 33 and a
lower chamber 331, a plurality of vertical partition broards 332, a
plurality of defining volume chambers 333 separated by the boards 332.
Each chamber 333 has a exit 334 in its bottom communicating with an exit
tube 35. A locating plate 34 is provided on a proper place of the chamer
body 31 for mounting a plurality of an pressure cylinders 34 respectively
connected cone-shaped press head 345 fixed at a lower end of the shaft 344
and a soft rubber cushion 346 on the press head 345. A spring tube 35 is
provided around the shaft 344 between the location adjusting nuts 343 and
the cone-shaped press head 345, having an upper flange 351, a coil spring
352 around the tube 35, a locating lower flange 353, and a cone-shaped
member 354. A pin 356 is provided to pass laterally through the shaft 344
between the locating lower flange 353 and the cone-shaped member 354,
having its both ends fixed on opposite sides of the slide cylinder 357 and
a non-rod air cylinder 36 is provided horizontally above the air cylinders
341, connected with an inverted U-shaped exit tube 361, which is then
moved horizontally back and forth above the material volume
pre-determining chamber 3 so that material stone fruit coming from the
conduit 26 may be dropped down equally around in the chamber 3 through the
inverted U-shaped exit tube 361.
An upper and a lower electronic eyes 37, 38 are provided in proper places
of walls of the body 31 for sensing material reserved in the upper chamber
33, sending a signal to the changeover valve 25 to permit an exit of the
blower communicating with the conduit 26 and to start the air pressure
vibrators 232 to work, moving the material in the tank body 21 through the
material dealing-out case 24, the hopper 241 into the conduit 26 by means
of wind force and then into the inverted U-shaped exit tube 361 connected
with the conduit 26 and finally dropping into the upper chamber 33 of the
chamber body 31. Then the material coming through the inverted U-shaped
exit tube 361 moved back and forth by the non-rod air cylinder 36,
dropping equally around on both sides of the cone-shaped cap 32 and into
the lower chamber 331 via an adjusting plate 321. When material is
accumulated to a height high enough for the upper electronic eye 37 to
sense out, the eye 37 functions to send out a signal to stop moving-in of
material therein.
Each exit tube 335 of the material volume predetermining chamber 3 is
placed to be located just above a blade frame of the planing device 4, and
a blade 41 is just placed under the exit of the tube 335. When the
adjusting plate 321 stops material 6 from moving in the lower chamber 331
and the air cylinder 341 is stopped, the slide cylinder 357 stops the exit
of the lower chamber 331. When the shaft 344 is pressed to move downward
by operation of the air cylinder 341, the location adjuster 343 is also
moved down to contact the upper flange 352 and continues to press it down
to a certain position where the top of the slide cylinder 357 reaches the
exit of the lower chamber 331 so that the material 6 may drop into the
slide cylinder 357 until the material 6 fills the slide cylinder 357, the
bottom of which is stopped by the cone-shaped member 354. If the air
cylinder 341 pulls up the shaft 344, the slide cylinder 357 goes up filled
with material 6, the cone-shaped mamber 354 stops at the position, and the
slide cylinder 357 continues to go up, with its upper surface passing
above the height of the material in the lower chamber 331 and with its
bottom passing above the cone-shaped member 354. Then the material 6 in
the slide cylinder 357 being of a definite volume drops through its own
open bottom in the exit tube 335. Then the soft cushion 346 with the press
head 345 is gradually lowered down to a lowest position by the shaft 344
pressed by the air cylinder 341, forcing the material stone fruit
gradually planed by the blade 41 in the planing device 4 until only a
layer of stone fruit is left in the exit tube 335. The pressure of the
press head 345 can be adjusted by an air pressure adjusting valve of the
cylinder 341. Then the shaft 344 is to be pulled up again by the air
cylinder 341. Then the same operation of carrying the material down to the
planing device 4 is repeated again and again, always leaving a layer of
material stone fruit in the exit tube 335.
The planing device 4 shown in FIG. 5 has a blade 41, an upper blade frame
42, a lower blade frame 43 and two rails 44, 44.
The blade 41 has a plurality of fixing holes 411, and two packings 412, 412
and a separating board 13 are placed on and under the blade 41, having
also a plurality of fixing holes 414 as those 411. The packings 412, 412
have a plurality of rectangular large openings 415.
The upper blade frame 42 and the lower blade frame 43 have the same shape
and size for pinching the blade 41, the two packings 412, 412 and the
separating board 413 between them to secure the blade 41, and having a
plurality of rectangular holes 421, 431 and reinforcing ribs 422 432. The
upper blade frame 42 has a plurality of holes 423 corresponding to a
plurality of threaded holes 433 that the lower blade frame 43 has so as to
assemble both frames 42, 43 together with screws. The lower blade frame 43
has three threaded holes 434 in the right and the left side for fixing
rolling shafts 436 pivotally connected with bearings 438, and a securing
member 435 on the middle of a rear side for connecting a gimbals 437 and
then with a air cylinder 439 mounted on the machine body 1.
The rails 44, 44 have a lengthwise groove 441 for the bearings 438 to slide
along therein, fixed firmly on adjusting plates 442, 442 mounted securely
on proper places on the machine body 1.
In assembling, referring to FIGS. 5-7, the planing device 4 is retracted to
a retreated position by operation of the air cylinder 439. At this
position, the material pre-determining chamber 3 has its exit above the
separating board 413, and the gap between them is higher than the
thickness of the packing 412 for material stone fruit to expose from the
exit tube 325 When the air cylinder 433 moves forward the planing device
4, the blade 41 begins to plan the stone fruit. As movement of the air
cylinder is fast, the blade 41 quickly planes proper thin pieces off the
stone fruit, which slide through the gap between the blade 41 and the
separating board 413, and then sucked on by a sucking plate 52 below the
board 413. Then planed stone fruit pieces are held to lie in order on the
sucking plate 52.
A sucking plate unit shown in FIGS. 8-14, is provided between the planing
device 4 and the baking plates 108, having an elongate turning cylinder
51, a sucking plate 52, a hole cleaner, a rotatable joint 54 and a lift
base 55.
The elongate turning cylinder 51 with a rectangular cross-section has an
air cylinder 511 in both ends and a vertical air cylinder 512 in its
interior and each cylinder 511 has a piston 513 to block or open an open
end of an orifice 515 of a side tube 514. Then vertical air cylinder 512
is connected with a connecting shaft 516, a horizontal rod 517 and then
the hole cleaner 53, which has many needles 531 to correspond to many
sucking holes 521. The size of the sucking holes 521 is a little larger
than that of the needles 531, which are inserted in or pulled out of the
sucking holes 521 by the vertical air cylinder 512. Then sucking plate 52
has a shallow recess on its upper surface. The rotatable joint 54 is of an
L shape, having one end pivotally connected with the side tube 514 of the
turning cylinder 51 and the other end connected with a blower via a soft
tube. A gear 543 is mounted around an outer surface of the side tube 514
to engage a gear 553 of a rotating cylinder 552 mounted on a slide plate
551. The rotating cylinder 552 to rotate the turning cylinder 51 for 180,
in other words, to invert it. The slide plate 551 is lifted up or lowered
down by an air cylinder 556 via a horizontal frame 555 and a slide groove
554.
In operating, referring to FIGS. 8-14, the sucking plate 52 is lifted up a
little below the blade 41, and when the blade 41 is gradually retracted
back, planed stone fruit pieces drop just the shallow recess 522 of the
plate 52. Meanwhile, the air cylinders 511, 512 all retreat back, and the
blower produces sucking wind to suck the planed stone fruit pieces on the
sucking plate 52. Then the air cylinder 552 operates to turn the turning
cylinder 51 with the sucking plate 52 for 180 to an inverted position
shown in FIG. 13 and the air cylinder 556 operates to move down the whole
turning cylinder 51 with the sucking plate 52 to about 2 cm. high above
the baking plate 108. And the air cylinder 511 moves its piston 513
forward to block the orifice 514 and consequently the sucking force in the
turning cylinder 51 disappears, permitting the planed stone fruit pieces
on the sucking plate 52 drop down in biscuit molds on the baking plate
108. At the same time, the vertical air cylinder 512 operates to lift the
needles 531 to insert in the sucking holes 521 to push small bits of stone
fruit 6 sticking there and on the shallow recess to drop down on the
biscuit molds 7. After that the needles 531 are retracted back, the
rotatable air cylinder 552 rotates back and the air cylinder 556 works,
rotating the whole turning cylinder 51 with the sucking plate 52 back for
180 to the original position to wait for the next operation.
While the preferred embodiments of the invention have been described above,
it will be recognized and understood that various modifications may be
made therein and the appended claims are intended to cover all such
modifications which may fall within the spirit and scope of the invention.
